How A Valve Guitar Amp Works.

Cool, I'm not sure if I've ever heard of 808 Valves, let alone seen any, but I'm guessing that they were probably similar to the EL84 Valves, a good friend of mine, who's a Luthier, is in the process of having a 5F3 built for him by someone, the 5F3 is another one of those classic Fender amps.

Just googled and edited my post, the power tubes were 807 pictured, although there was such a beast as an 808

Geez, that's a pretty hefty Power Valve, I bet your AC30 build put out a decent amount of power and was pretty loud, how many of those 807's did you use to build your AC30?, that looks like a standard Radio-Transmitter Valve.

It was a very basic single channel amp with simple tone controls and no effects 2x807 in PP, 30watts rms.

In 1965 it was a very loud amp but by about 68 and the birth of heavier rock it had nothing, hence the hike up to the Lenard 150W

You probably could have been able to increase the output power by upping the HT and upgrading the output transformer, I think from the looks of it, you probably could have been able to easily get something like 100 Watts from out of two 807 Valves in Push-Pull, I've seen a single-ended Valve amp that uses a single 813 Valve and the HT was something like 1000V DC, or there abouts, but the amp was a high-end HiFi amp.
